Prednisolone shown to be teratogenic in mice when given in doses 1-10 times human dose; dexamethasone, hydrocortisone, and prednisolone were ocularly applied to both eyes of pregnant mice five times per day on days 10 through 13 of gestation; a significant increase in the incidence of cleft palate observed in fetuses of treated mice; there are no adequate well-controlled studies in pregnant women; prednisolone should be used during pregnancy only if potential benefit justifies potential risk to fetus
Lactation
